How do you find main Idea?

Main ideas are often found at the beginning of paragraphs. The first sentence often explains the subject being discussed in the passage.

Main ideas are also found in the concluding sentences of a paragraph. The main idea can be expressed as a summation of the information in the paragraph as well as a link to the information in the next paragraph.

The main idea is found by looking at the general idea of the text you are reading, what is it about? What does it mention?
